This is perfect example of what is called. Mottainai
Mottainai Defined (www.wehatetowaste.com/mottainai)
Mottainai, literally meaning ‘essence’ is an ancient Buddhist term that translates into having respect for the resources around you, to not waste these resources and to use them with a sense of gratitude. Mottainai is closely associated with the conservation practices that we recognize in the West as the three R’s – reduce, reuse, recycle – with a fourth R added: respect. The respect practice stems from the Shinto belief that objects have souls (possibly those of one’s own ancestors) and therefore should not be discarded.
